    Does anyone know of a good JUnit test generation tool?

    I'm looking for a tool to generate unit tests (pref. JUnit) for a given Java code base.
    It is meant to be used by students in a course on s/w reverse engineering and reengineering. The student will explore various tools (e.g., metrics, style).
    In the past, I tried AgitarOne to generate tests, but those tests require a specific plugin just to run them and do not seem to work with standalone tools outside its suite (e.g., EclEmma). Besides, AgitarOne is rather heavy and its usage policy of for academia is rather restrictive.

    Does anyone know of some tool that does not have such problems?

    Who has an experiment design for Software Architecture BSc students?

    This year, I give a lecture on software architecture for BSc students. I'm still looking for some "action" for the students, and I want to replace 2-3 exercises (4-6 hours) by an experiment. Does anybody has a design for an experiment on UML modeling? For instance, an experiment that waits for replication?

    Thanks Marco

    Hi Maya,

    Unfortunately, I had to postpone as I had to improve some programming-related skills first. I plan to reorganize this course somewhat to get more space for this, and will execute it next winter. However, I have the basic idea (solution development using design pattern). Do we want to talk about that to detail that out and to create a joint experiment design, which you carry out first? If you want, I can send you (next week after all the exams) the basic stuff..

  • Stephane Maag added an answer:
    How can I create state model representation in Model based testing?

    Model based testing is a derivative of Unified Modeling Language (UML) concepts. Usually state machine diagram, interaction diagram etc are used to represent the behavior of system. ATM, Elevator, Vending machines are popular examples for deriving these diagrams. I think these examples are easy to represent in UML diagrams because they contain states and transition. What about other examples which doesn't have explicit state or transition? Like triangle program, sorting problem or search program etc. How can I represent them with state machine?

    Stephane Maag · Institut National des Télécommunications

    A state machine (from UML or others such as SysML or SDL that is more 'formal') is no more than a set of states and transitions. In your case, a state can be seen as a vector of the valuated parameters of your program. Transitions like actions that make this vector changes. Then, you have your FSM!

    This is the way we used in our papers: Ana R. Cavalli, Stéphane Maag, Gerardo Morales: Regression and Performance Testing of an e-Learning Web Application: dotLRN. SITIS 2007: 369-376, and Gerardo Morales, Stéphane Maag, Ana R. Cavalli, Wissam Mallouli, Edgardo Montes de Oca, Bachar Wehbi: Timed Extended Invariants for the Passive Testing of Web Services.

  • Marcelo Negri Soares added an answer:
    What is the substitute for UML?
    Is there another methodology that replaces UML?
    Marcelo Negri Soares · Universidade Nove de Julho

    Object Process Methodology is an alternative. Taught in some CS courses including a couple at MIT.

    Object process methodology (OPM) is an approach to designing information systems by depicting them using object models and process models. OPM was conceived and developed by Prof. Dov Dori, at the Technion – Israel Institute of Technology. A paper that first presented ideas underlying OPM was published in 1995. The comprehensive resource is Dori's book Object-Process Methodology – A Holistic Systems Paradigm.

    CUDA - Is it worth it to unwind a static loop?
    Is it worth it to unwind a static loop with a lot of branches?

    I have a static loop with a lot of branches inside. If I unwind it, and flatten out obvious branches, it becomes sequential code. Is branch prediction good enough to avoid following every single path in each iteration of the loop or do I have to do that manually by unwinding the loop?
    Matt J Harvey · Acellera Ltd.

    Can be. You can coerse the compiler to unroll a for{} loop for you using "#pragma unroll". You'll find the details of that in the Cuda Programming Guide.

  • Hajara Innyah Abdulwahab added an answer:
    Which are the formal ways for defining a concrete syntax in language engineering?

    Meta modeling has been defined as the the formal way for defining an abstract syntax of a domain specific modeling language, no specific method has been formalized for the definition of concrete syntax. Though some researchers have define the concrete syntax of their language based on their own informal definition of the concrete syntax. Dear all is there a formalized way for defining a concrete syntax of a language (the concrete syntax here in question  is a graphical  concrete syntax).

    Dear all, I had asked the question above few weeks back.....

    What are your views on metamodeling the concerete syntax?

  • Farzaneh Moradian asked a question:
    Can anyone send me ideas about malware propagation models optimization under cloud or new methods in this field.?

    Cloud-based Two-stage revised worm-anti-worm (Re-WAW) is one of models that I studied. The two-stage Re-WAW model uses the proactive and passive switching defending strategy to achieve the worm propagation containment and clear off the benign worms. The mathematical modeling and simulation results have demonstrated that the cloud-based and the two-stage Re-WAW models not only contain the worm propagation, but also reduce the overall consumption of network resources. Some shortcomings in this cloud-based benign worm countermeasure technique should be overcome. The first is to quickly generate the corresponding benign worm for the 0-day worm which attacks susceptible hosts in unknown vulnerabilities and methods. Second, it generally requires considerable number of machines in the cloud to achieve better containment of the malicious worm as the initial benign worm infected ones. The third is that it is still a controversial issue to use the benign worm to strike back the malicious worm. In addition, some challenges, such as patching safety, network congestion, and legal issues, on the benign worm need to be addressed.
    I don't know how :
    1. to quickly generate the corresponding benign worm for the 0-day worm
    2. to decrease number of machines in the cloud to achieve better containment of the malicious worm as the initial benign worm infected ones
    3. to use the benign worm to strike back the malicious worm
    4. to Dealing with the challenges such as patching safety, network congestion, and legal issues, on the benign worm need to be addressed.

    Thank you for your attention.

    Is there any class diagram alike diagram for C code?

    Class diagram is used for Object oriented program like C++, Java etc. How can I represent it for C code? C code doesn't have class but they have functions. Each function have variables and other calling function. I want to represent the relationship between functions with variable and calling function. How to do that and what can we call that diagram?

    Thanks~~

    Andrew Stephen Dent · Touchgram Pty Ltd

    Just run Doxygen over your C code with a default configuration plus change the EXTRACT_ALL option to YES. You can do this in the GUI that comes with the installer.

    http://www.stack.nl/~dimitri/doxygen/

    It groups C functions by file.

    For more diagrams, turn the CALL_GRAPH and CALLER_GRAPH options on.

    How should I audit microsoft os and office softwares?

    Genuine software procurement is a challenge because, various measures taken by Microsoft can be bypassed and let users believe that they are using genuine products. As an auditor of information system what can one look at to ascertain genuine licensing?

    Rod Sheaff · University of Plymouth

    Compare them with alternatives such as LibreOffice in terms of

    1. Functionality your organisation(s) require.

    2. Use of standardised protocols and document formats

    3. Licensing and re-use restrictions

    4. Cost

    See

    Aspect-oriented programming (AOP) is a novel topic in the software engineering and languages communities. AOP appears to have the potential to significantly improve the reliability of programs, particularly by modularizing error-handling policies and allowing for easier maintenance and better reuse. In this article, we introduce AspectJ, the first AOP language, and demonstrate how you can use it to construct more reliable software

    Is there empirical evidence supporting process-oriented software engineering?

    Many researchers in academia and at least some practicioners take it for granted that  development processes (be it rigorous or more agile) are a key factor for successful SE. It seems that we keep also telling that our students. 

    Is anyone aware of good initial readings about empirical studies that shed light on the actual effectiveness of software processes rather than claiming it?

    What's the best approach in this problem using Particle Swarm Optimization?

    Hello!

    I'm currently revising my optimization algorithm for a specific part of a problem. I have trouble in wrapping my head around a new approach and my mind is having this tunnel-vision of ideas. I could really use some fresh perspectives.

    I'll try my best to simply the explanation.

    (Please see attached file "Example-1.png" and "Example-2.png")

    -------------------------
    Say, we are given 3 distinct persons.

    Each of these person have a specific Supply (an item that he/she possess) and a Need (an item that needs to be acquired). Now, if these Supply-Need is reversed, and their reverse can be found in another person, they can be traded.

    Moreover, the pairs have a numerical value called Gravity that specifies the importance of the pair to the person. We can treat it as a weight on how much a person can be "satisfied" if the Supply-Need pair is met. Each person can only allocate and distribute 100-points of Gravity among all of his/her Supply-Need pairs.

    Now, the Total Satisfaction of this process can be computed by getting the sum of all the Persons' individual satisfactions.

    The objective is to have the group of Persons trade their Supply-Need pair/s in different combinations such that we can acquire the largest Total Satisfaction as possible.
    -------------------
    In PSO, each Particle represents a candidate solution based on its location in the Search Space.

    Given the attached examples in this post, we can say that Example-1.PNG is a distinct candidate solution to this problem, as well as Example-2.PNG.
    -------------------
    What's the best approach in how this problem can be represented and evaluated by a Fitness/Objective Function?

    How would you characterize this problem in PSO?

    Do you have any recommendations of published work with the same problem as this?

    Cheers!

    What are the factors that influence the effectiveness of a virtual team in global software development projects?
    Being the project manager of a team that includes remote members has additional challenges compared to managing co-located team members.

  • Stefan Schuerger added an answer:
    Can we take bug priority as a deciding factor in the bug severity prediction?

    We are developing severity prediction models. Can we take bug priority as a deciding factor in the bug severity prediction?

    Stefan Schuerger · Vodafone Group Germany

    Priority, severity and fixing effort are three different things. It helps to stick to a proper definition, such as ISTQB's:

    severity = The degree of impact that a defect has on the development or
    operation of a component or system [after IEEE 610].

    priority = The level of (business) importance assigned to an item, e.g. defect

    severity and priority usually correlate, but they don't have to. Priority can be somewhat arbitrary, unless strictly defined in a contract, such as an SLA.

    Fixing effort is totally independent. Believe me, the worst bugs (in terms of effort) are often the low-priority ones - also, because they usually get pretty old before being fixed.

    2. Generate Trial Points
    3. Obtain Stage 1 Start Point, Run
    4. Initialize Basins, Counters, Threshold
    5. Begin Main Loop
    6. Examine Stage 2 Trial Point to See if fmincon Runs
    7. When fmincon Runs
    8. When fmincon Does Not Run
    9. Create GlobalOptimSolution
